I just recorded over an hour long intricate tutorial only to find when I was done and hit save and edit- the microphone was not associated. Camtasia doesn't seem to remember what microphone you used last and always reverts to the default (which I have taped up even), I even checked before recording but had to turn off and back on the software and this apparently reset the device- so I was talking to nobody the whole time, and my perfect video recording is useless mime chit... sigh... but... I jumped in right away and started over- this time I was more efficient, but my frustration was boiling... thought I'd share. BTW version 8 is the god of recording software, makes 7 look like a mere mortal.
